does licence required for below one watt and 1 km range fm transmitter in india.

I am a hobbyist and freelancer.
Some students form an engineering collage requested me to help them setup a campus radio.
Does a below one watt and below 1 km fm transmitter bring legal issues if they dont interfere with other broadcasting ?

Thanks

Here in the US we have 'micropower' FM broadcasting. As I understand it, anyone can transmit as long as the frequency has no other stations on it. Power can be sufficient to cover a mile or so.

Don't know about India, however. Try to find a local club of Ham (shortwave) radio operators. They are likely to have correct information, rather than the municipality.

It is very important that your transmitter broadcast a 'clean' signal, on one frequency, free of distortion. If your signal is not clean, then you are transmitting noise somewhere on the frequency spectrum. It may interfere with your neighbors picking up radio and tv programs. Then you're in trouble with the authorities.

All transmitters require a 'license' except in the 'license-free' frequencies.
The agency in India which regulates & monitors this is the WPC (Wireless Planning & Co-ordination wing)
check out the website http://www.wpc.dot.gov.in/Home.asp

here is the frequency plan document http://www.wpc.dot.gov.in/Docfiles/N...0Plan-2011.pdf

so you are positive that it will bring legal issues if we setup a small transmitter whose signals never leaves campus and never interferes with others ?



If we follow strict rules here it would require a permission of about 6 government agencies to put a cfl in our homes. :)

you cannot guarantee that, RF signals don't just stop at a certain distance. .... they continue on and on getting weaker as they go
you could end up interfering with other people's radio reception several kilometres away from your transmitter

This is why govt agencies require licencing and testing of transmitting devices

I only cited the law.
It's up to you whether you want to chance it.

Here are three links which can give you sufficient information about licensing.

My take is that the license is necessary - but you may read the fine print to make your own decision.

there is no fine print

Amateur radio and campus radio are completely different subjects.

In any case, a license is needed. Transmitting without a license is illegal, no matter if it actually causes interference or not. Over here in Germany, I know a guy who ignored that licenses topic, built a campus radio and had very serious trouble. I strongly advise to forget about this idea. Do live streaming on the internet or something like that, but don't run an illegal transmitter. It's not worth the trouble and fines.

Further to this point, I came across some very interesting information for the OP, which EXACTLY addresses their needs. Dunno why this never came to my attention before....
